IMPROVEMENT IN NURSING-BOTTLES.

Specification forming part of Letters Patent No. 139,958, dated June 17, 1873; application filed June 2, 1873.

To all whom it may concern:

Be it known that I, WILLIAM HOBSON, of Sandwich, of the county of Barnstable and State of Massachusetts, have invented a new and useful Improvement in Nursing-Bottles; and do hereby declare the same to be fully described in the following specification and represented in the accompanying drawings, of

Figure l is a front elevation, and. Fig. 2 a vertical section of a nursing-bottle provided with my invention. Fig. 3 is a side view of the flanged draft-tube of such bottle.

My invention consists in a flanged drafttube, an elastic nipple, and a cork, arranged together and with the bottle-neck in manner as represented in the accompanying drawings, in which- A denotes the flanged draft-tube, B the elastic nipple, O the cork, and D the bottle having a neck as provided with aflange, b. In the arrangement of the said parts the cork encompasses the draft-tube and the nipple is drawn over the mouth, and about and underneath the flange c of such tube so as to insulate the flange from contact with the mouth of the glass bottle, the cork serving to hold the tube in place within the bottle-neck.

In the ordinary way of applying the glass draft-tube to the-bottle, the flange of the tube,

has rested directly upon the mouth of the bottie, the nipple being drawn over said flange and the flange of said mouth, so as to hold the two flanges in connection, and stop or cover the joint between them. This method of connecting the tube to the glass bottle, viz.,

by means of the elastic nipple stretched over the two, is very liable to cause breakage of the tube or its flange, and has resulted in a serious loss as well to the manufacturer as to the seller and purchaser or user of the bottles.

By supporting the glass tube wholly out of contact with the glass neck of the bottle, or insulating it therefrom both by a cork and by the elastic nipple applied to such tube as set forth, the. danger of breakage of the tube, either while applying it to or removing it from the bottle-neck, is practically overcome. While pressing the cork into the bottle-neck, the flange of the draft-tube. cannot be forced in contact with the neck, for a portion of the nipple will be between the two and operate as an elastic cushion or insulator to protect the flange from being broken.

I am aware that it is not new to fix a glass tube in the neck of a bottle by means of a cork inserted in the neck and encompassing the glass tube therefore I make no claim to such. Nor do I claim a flanged draft-tube, nor an elastic nipple applied to a bottle by drawing the nipple around the flanges of the tube and the bottle-neck.

What I claim as my invention is as follows:

The flanged draft-tube A, the elastic nipple B, and the cork 0, arranged together and in or applied to the neck of a bottle, in manner substantially as represented in the drawings, and hereinbefore explained.

WILLIAM HOBSON.
